  # Skip this for native application as Zephyr only provides
  # additions to the host toolchain linker script. The relocation
  # sections (.rel*) requires us to override those provided
  # by host toolchain. As we can't account for all possible
  # combination of compiler and linker on all machines used
  # for development, it is better to turn this off.

  # CONFIG_LINKER_ORPHAN_SECTION_PLACE is to place the orphan sections
  # without any warnings or errors, which is the default behavior.
  # So there is no need to explicitly set a linker flag.
